Since I want to take advantage as much as possible of the space in a poster I'm making I want to make the footnotes (that include citations) appear continuous (in one line). After searching I found this post that says that I can achieve that using the footmisc package.

The problem is that when I use it, my footnotes disappear. Consider the following example code. If you remove the \usepackage[norule,para]{footmisc}, the footnotes appear properly.

Using \cite inside \footnotetext instead of \footcitetext and what you said worked. Also using the answer from this post (tex.stackexchange.com/questions/21913/…) I managed to make the line disappear. Cheers mate. You should change your comment to an answer.
